Abstract
A solar powered ventilation device for a vehicle has a solar cell disposed on a car body and electrically connected to an electrically operated ventilation system, and a controller for detecting a predetermined temperature outside the car to electrically disconnect the ventilation system from the solar cell. The ventilation system is supplied with electric power from the solar cell, thereby ventilating or exhausting air from the vehicle interior only when the exterior temperature is higher than the predetermined temperature.
